There will not be one fuel of the future.  Our transportation and energy needs will be supplied from a diversified portfolio of sources.

 Examples of future "fuels" (energy storage mediums):

  • electricity
  • biodiesel (derived from algae)
  • compressed air
  • hydrogen 
  • human power! (bike and walk)
  • wind (for over seas shipping)
We capable of greatly reducing our fuel requirements by designing our cities and communities around public transit, walking, and biking.  There is not enough discussion about ways to reduce our fuel needs!
